Individual Differences in Self-Talk Frequency: Social Isolation and Cognitive Disruption
2019
Despite the popularity of research on intrapersonal communication across many disciplines, there has been little attention devoted to the factors that might account for individual differences in talking to oneself. In this paper, I explore two possible explanations for who people might differ in the frequency of their self-talk. According to the “social isolation” hypothesis, spending more time alone or having socially-isolating experiences will be associated with increased self-talk. According to the “cognitive disruption” hypothesis, having self-related experiences that are cognitively disruptive will be associated with increased self-talk frequency. Several studies using the Self-Talk Sc…
High-contrast sub-Doppler absorption spikes in a hot atomic vapor cell exposed to a dual-frequency laser field
2017
International audience; The saturated absorption technique is an elegant method widely used in atomic and molecular physics for high-resolution spectroscopy, laser frequency standards and metrology purposes. We have recently discovered that a saturated absorption scheme with a dual-frequency laser can lead to a significant sign reversal of the usual Doppler-free dip, yielding a deep enhanced-absorption spike. In this paper, we report detailed experimental investigations of this phenomenon, together with a full in-depth theoretical description. It is shown that several physical effects can support or oppose the formation of the high-contrast central spike in the absorption profile. The physi…
Constitucionalismo y poder negativo. Una aproximación a la protesta social como contrapoder
2022
Esta tesis propone una aproximación a la protesta social desde una comprensión constitucional del concepto de contrapoder. Tomando al concepto de soberanía como pieza central del aparato teórico del derecho público, este trabajo desarrolla una línea argumentativa que propone que la historia de la soberanía es una historia que tiene dos caras: una cara del poder, por una parte, típicamente identificada con la historia de la construcción del Estado y de las formas de legitimación de la autoridad; y una cara del contrapoder, por otra, que remite a la historia de las luchas y conflictos sociales que han jalonado múltiples transformaciones en la constitución material. Se analiza, en primer lugar…

Coralli trapanesi nella collezione March
2016
Il volume tratta le opere trapanesi in corallo della collezione March, battute all''asta presso la sede londinese di Christie''s il 16 giugno 2015. Si tratta di esemplari di diversa tipologia, sia a carattere sacro che profano, che contribuiscono ad arricchire il catalogo della produzione trapanese in corallo tra XVI e XX secolo, attestandone ancora una volta l’eccezionalità nel contesto dell’area mediterranea e l’alto livello di esecuzione raggiunto da questi artisti. La preziosità di questi manufatti viene ulteriormente confermata dalla loro presenza in una prestigiosa collezione privata insieme ad esemplari di grande valore artistico come dipinti, sculture, arazzi, arredi ed opere d’arte…

Crystal structure of N′′-benzyl-N′′-[3-(benzyldimethylazaniumyl)propyl]-N,N,N′,N′-tetramethylguanidinium bis(tetraphenylborate)
2015
In the crystal structure of the title salt, C24H38N42+·2C24H20B−, the C—N bond lengths in the central CN3unit of the guanidinium ion are 1.3364 (13), 1.3407 (13) and 1.3539 (13) Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a nearly ideal trigonal–planar geometry and the positive charge is delocalized in the CN3plane. The bonds between the N atoms and the terminal methyl groups of the guanidinium moiety and the four C—N bonds to the central N atom of the (benzyldimethylazaniumyl)propyl group have single-bond character. In the crystal, C—H...π interactions between the guanidinium H atoms and the phenyl C atoms of the tetraphenylborate ions …
